IMPROVEMENT IN COOKING-STOVES.

Specication forming part of Letters Patent No. 120,840, dated November 14, 1871.

To ali whom it may concern :V

Beit known that I, JOHN W. O. WEBB, of Gel dar Rapids, in the county of Linn and State of Iowa, have invented a new and useful Improvement in Cooking-Stoves, of which the following is a specification:

In the accompanying drawing, Figure l represents a side elevation of my improved stove when used for cooking purposes, a portion of one side of the hot-air chamber being removed to show the interior pipes. Fig. 2 represents a top view of the stove with the oven removed. Fig. 3 represents a partial bottom view, showing the perfor-ations d,-Which communicate with the heatingchamber A, and the slides for regulating the admission of air to said chamber.

My improvements consist of a removable oven having an open bottom for the purpose of receiving the hot-air directly into the cookingchamber from the heating-tubes, which pass through the hre-chamber, thereby retaining the heated air Within said oven, instead of causing it to pass around it and escape. My improvement also consists in providing the bottom of the heating-chamber with a series of openings arranged between the rows of air-heating tubes for the purpose of regulating the heat of the tubes and the air passing through them, which is very desirable in cooking.

In the drawing, the hre-chamber of the stove is extended back so as to form a heating-chamber, A, Fig. l, through which passes a series of vertical tubes, B, open at the top and bottom plates of the stove, so that the heat from the hre-chamber, in passing oft', heats the tubes B and the air passing through them. From the top of the stove hot-air is constantly passing out of y( the tubes B; andas the oven E is arranged to be iitted thereon over these tubes I construct it without a bottom, so that the heat from the tubes must pass directly into the oven to effect the cooking. The oven E has a plate, F, arranged near its bottom, with openings c all around it, so that the heat from the tubes strikes the plate F and ascends into the oven through the openings c, as shown by arrows in Fig. l. The oven may be provided with one or more sliding shelves, G; and it is made detachable from the stove, being held in place by iianges or other suitable means. The top plate C oi' the stove may have the usual openings c for cooking purposes, as shown in Fig. 2. rlhe bottom plate D oi' the heatingchamber A has openings d arranged between the open ends of the tubes B, communicating with the heating-chamber A, and covered with slides d', which, when drawn out, allow the cold air to enter the chamber A through the openin gs d around the tubes B, and thus regulate the heat passing through the air-tubes, as Well as that in the chamber A.

Having described my invention, I claim- 1. The oven E, without bottom, and arranged to receive the hot-air directly from the tubes B, as described and represented in Fig. 1 of the drawing.

2. The openin gs d and their covers df, arranged between the air-heating tubes B for the purpose of regulating the heat of the tubes B, as -described and shown in Fig. 3 of the drawing.
